asterisk users - Jan 2010 - Inserting white noise / music / sound file into mixmonitor

A week or so ago, I explained that we need to "blank" our call
recording when some sensitive information like credit cards where
being discussed. With the lists help, I managed to find the pause/
unpause  monitor commands. That works great. However (there is always
a however), what that now means is that the length of the call does
not match the length of the call recording, so adding stuff like "this
happened at 11:04 into the call" now is out by the length of time of
the pause :(

I was wondering if it was possible to replace the voice on either leg
with a sound file or something, but only in mixmonitor, as we
obviously need to hear the person talking in order to take the
details.

Here's one possible work-around;  Since you have the length of the call
(from the CDR) and know the size of the "Gap", you could use SOX to
split
the .wav file into 2 segments, then reassemble with one of the music-on-hold
files segmented into it.
